The American Museum of Natural History holds a series of podcasts about science.

The particular podcast I listened to was 1hr and 22 minutes long and was about the approach of Peter Sagan to science and religion and the overlaps, differences and Carl's overall opinions on the topic of god, God and science.

It is a fascinating, gentle and calm discussion of Carl's former colleague, wife and the moderator. They manage to portray Carl's own position, the way he argued for it and the way he would answer to classic rebuttals. His thesis was that intelligent design (new name for creationism) is not correct, however that the science itself - in its mere 4000 years of studying the Earth - is perhaps as close to some Truth about the cosmos as is religion. The difference is that science does not claim it knows the unknown, where else most religions do.
